"my easy answer/defense is that i am a hopeless romantic"
Really? Why wouldn't a hopeless romantic hold out for a guy who behaves in a romantic way towards her???
I'm not buying it. You'll have to dig a little deeper my dear.
The wounds from your marriage are not even close to healed. Maybe this relationship was a substitute for the previous one, in that if you could get THIS guy to love you, it would be sorta like the equivalent of winning back your ex?
